Catalogue 9 - STAUFF Filtration Technology

www.stauff.com/9/en/#37 C 37 Product Description STAUFF SF series High Pressure Filters are designed for in-line hydraulic applications, with a maximum operating pressure of 420 bar / 6000 PSI. Used together with STAUFF SE series Filter Elements, a high efficiency of contaminant removal is assured. The high dirt-hold capacity of the elements ensures long service life and, as a result, reduced maintenance costs. High Pressure Filters § Type SF Technical Data Construction Designed for in-line assembly, with threaded mounting holes on top of the head.

Operating Pressure Max. 420 bar / 6000 PSI Burst Pressure Min. 1260 bar / 18275 PSI Temperature Range -20 °C ... +100 °C / -44 °F ... +212 °F (Short term up to +110°C / +230 °F) Filter Elements Specifications see page 40 Media Compatibility Mineral oils, other fluids on request Clogging Indicator HI Filter Head Valve IB Filter Element SE Filter Bowl Options and Accessories Valves Bypass valve: Allows unfiltered oil to bypass the contaminated element once the opening pressure has been reached, a differential pressure of 6 + 0,5 bar / 87 + 7.25 PSI ∆p is the standard setting. Other settings available upon request. Reverse flow valve: Allows reverse flow through the filter head without backflushing the element. Non-return valve: Prevents draining of the delivery line during element change. Multi-function valve: Opening pressure 6 +0,5 bar / 87 +7.25 PSI Bypass, reverse flow capability and non-return valve combined in one valve. Clogging Indicators Standard actuating pressure: 5 -0,5 bar / 72.5 -7.25 PSI ∆p Other actuating pressure settings are available upon request.
